Existing industrial luminaires (e.g. for car parks, factories and loading bays) are often functional at the expense of being esthetically pleasing, and are also expensive to install. The Pacific LED luminaire addresses all these issues by combining minimalist design with quick, easy and thus less expensive installation, dramatically reduced running costs and maintenance requirements typically 50% less than with traditional solutions. Its visual simplicity is married with breakthrough ergonomic elements, such as a twist-to-open locking device, pull-to-release mounting brackets and a printer cartridge style release handle.
